Let me tell ya'all where we stand today france stands neck to neck. They have achieved similar features in 80s & 90s however duration of there scramjets in unavailable also since then what progress they have done isn't much available in public. And we always forget japan, they do have such tech. They also have brahmos like asm.

I would be making a detailed post covering all nations.

If you wanna go into past, that russia/Soviets made most progress in scramjets.

But except, India declared 1000+second test today.
No other country publicly declared or have any record that can points towards scramjet burn time if more than 300+ seconds.

US holds the record for 210second scramjet burn time, longest in history publically.
Before we declared our.

I would be interested to know fuel used in the 1000 sec burn. If its hydrogen (like what the previous HSDTV demonstrator had) then there is still some way off before we drop the engine into a missile.

Kerosene, however, would be crazy.

I dont think Previous demonstrators would have had it's too difficult to handle however it's properties are the most desired ones in such applications. In such applications ethylene is most preferred Americans use ethylene. However it's not just one fuel it's mixture of alkenes, alkynes & hydrogen. However this are not filled in missile but rather produced from jp (kerosene) fuel.
Because alkane, alkynes can't be used as endothermic fuel.
Here's details explanation.

Yeah it's crazy we use kerosene.

I find some of this dubious, but the word choice is confusing so it could be a misunderstanding on my end.

Are you saying that the kerosene fuel is broken down to form these mid flight? Very dubious imo.

Last credible report I saw was of us using h2 as fuel, and that ISRO test with kerosene as fuel was pending. H2 is obviously simpler, no coking, simple fuel mixing, etc. I didnt see anything in your previous post about us having functional kerosene scramjets.

Except for his voice , especially the way he enunciates , by far Ameit Kashyap's Defence Decode is probably the best defence channel out there for technical matters.
